Subject: [PATCH 1/2] dt-bindings: iio: sx9324: Add CS idle/sleep mode
Date: Mon, 2 May 2022 17:41:55 -0700 [thread overview]
Message-ID: <20220503004156.3559940-2-swboyd@chromium.org> (raw)
In-Reply-To: <20220503004156.3559940-1-swboyd@chromium.org>
We need to configure the sleep and idle mode of the CS pins for this
device. Add a DT property to do this so pins are in a proper state
during sleep (either hi-z, grounded, or pulled up to vdd).
